The principle of 16Mn 12Cr1MoV T91 27SiMn 30CrMo 15CrMo 20G Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV palladium tube purification hydrogen is that hydrogen is adsorbed on the palladium tube wall when the purified hydrogen is passed into the palladium tube at 300-500 C, and it can produce an unstable chemical bond with hydrogen (palladium) because the palladium's electron layer lacks the electron. The reaction with hydrogen is reversible). Under the action of palladium, hydrogen is ionized to a proton with a radius of 1.5 x 1015m, and the lattice constant of palladium is 3.88 x 10-10m (20 C), so the palladium tube can be passed through the palladium, and the proton is combined with the electron and reformed the hydrogen molecule, escaping from the other side of the palladium tube. On the surface of palladium tube, the dissociated gas is not permeable, so high purity hydrogen can be obtained by palladium tube. Although palladium has unique permeability to hydrogen, pure palladium has poor mechanical properties, easy oxidation at high temperature, low recrystallization temperature and easy to deform and embrittlement of palladium tubes, so palladium can not be used as a permeable membrane. Adding a proper amount of IB and VIII in palladium to make palladium alloy, it can improve the mechanical properties of palladium. 11. seamless steel tube (GB3088-82) for automobile semi axle sleeve pipe (GB3088-82) is a high quality carbon structural steel and alloy structural steel for manufacturing automobile semi axle casing and driving axle bridge shell. Silver accounts for about 20-30% and other components. Such as gold, etc.
